I think it is a geocentric model
Acceleration is non zero but the velocity is zero.
Answer: Option 2.
<u>Explanation:</u>
Acceleration is the speed that an object gains with in a short period of time. In the language of Mechanics, Acceleration is the change in the velocities of the objects with respect to the time. So when a ball is thrown up in the air, there will be some acceleration and there will be some speed that the ball will gain when thrown up.
Velocity is the speed of an object but in a particular direction. Velocity of an object is the rate of change of the position of the object with respect to the frame of reference of that frame. So the velocity of the ball up in the air is zero.
